The present invention relates to a thermally insulating molded part comprising an upper part (7) and a lower part (8), wherein according to the invention, the upper part (7) and the lower part (8) have a cavity therein. It is designed as an integral injection-molded or die-cast part, and the cavities are designed as chambers 3 which are separated from each other in an airtight manner. In a corresponding method for producing such insulating molded parts, in the first method step within the context of an injection-molding or die-casting process, the composite material of the upper part 7 is combined with additives made of natural or recycled materials. Introduced into the first mold and in a second method step within the context of the melt-core process, the composite material of the lower part 7 is introduced into the second mold together with additives made of natural or recycled materials, wherein The two molds comprise a fusible core with individual melts connected to the outside by openings 1 in the second mold, and after the second method step, the melts melt to form individual chambers 3. |
